S09 3.3V Step Up/Down Converter 3-15V to 3.3V 600mA

The S09 is a DC-DC voltage converter that can automatically switch between Step-UP (boost converter) and Step-Down (buck converter). The maximum input voltage is 15VDC, and the quiescent current is less than 200uA. The regulated output voltage is 3.3V with a maximum output current of 600mA. The board includes an Enable Pin (EN) that allows you to turn the converter on and off. If you want the converter always on, you must connect EN to VN+. This converter module is perfect for supplying power to an ESP8266 or ESP32. You can also additionally connect a capacitor in parallel to the output for voltage stabilization.
